On August 30,
1968
Soviet Government issued a directive №670-241, setting timeframe for new generation of Soviet unmanned
reconnaissance drone Tu-143, part of the tactical reconnaissance system «Reis» VR-3 («Рейс» ВР-3).
Variant with photo reconnaissance capability had to be ready in the
1970
and one with TV cameras and radiation sensors - in the
1972.

Autonomous mobile systems were already in service with Soviet armed forces:
La-17R and Tu-123 Yastreb/Hawk (Ястреб).
Those UAVs had a common disadvantage: they had no landing equipment (except of sensor/records compartments) and
were not designed for multiple use. First successful multi-mission UAV was
Tu-139 Yastreb-2 (Ястреб-2). This 13,500kg aircraf could land on
unprepared field and used again. But it did not satisfy new demands of the military:

navigation system has to guarantee return of the UAV to 500x500m landing area

high readiness, short reaction time

Tu-143, its launcher and land control unit were developed in a very short time.
First successful flight was performed in December
1970.
State Acceptance trials began in
1972,
and pre-production batch of 10 UAVs started in
1973
at Kumertau (Bashkiria, Bashkortostan). In
1976
the "Reis" system was adopted by military. It was in production until
1989,
and 950 aircraft were built.

Tu-143 is all metal, highly versatile reconnaissance
aircraft that could take-off from just about anywhere. It was configured for
reconnaissance in difficult terrain conditions and heavy air defense activity.
The UAV has a monoplane tailless delta scheme, with a tapered wing and fixed
delta canards. Used material include D-16 duralumin and AMG-6 magnesium alloys,
as well as fiberglass with honeycomb filler.
It is propelled by a TR3-117 jet engine manufactured by Klimov NPO
and a single solid rocket booster.

The aircraft is launched by the SPU-143
system mounted on VAZ-135 multi-purpose truck and is recovered with a parachute.
The launcher is reloaded using the TZM-143 transport / loader vehicle.

"Reis" was adopted by army, and soon proved to be superior to manned
reconnaissaters (assuming that they carry similar information gathering equipment). The key to
success was an advanced guidance system able to use nap-of-the-earth flight. It guaranteed a more
precise approach to designated area, especially in cases when multiple areas had to be observed.

The Tu-143 is a semi-stealth system, reducing the effectiveness of radar and
radar-guided missiles by one level, and IR systems by one level. It also became the first one
liberally sold to allied countries throughout the world. The aircraft saw combat action over Israel in
1982
(operated by Syria). Israeli air defenses knew about Tu-143 but were never able to detect or shoot down
one. It also was mentioned that Tu-143 was operated in high mountains, taking off and landing at
elevations up to 2000m and flying over mountain ranges as high as 5000m. Was it in
Afghanistan?

Landing of the Tu-143 is a multi-step procedure. After aircraft enters landing zone,
the engine is cut off. Steep climb and brake parachute slow it down, and after about 11sec brake
parachute is jettissoned and replaced with landing one. When descent is vertical, landing parachute is
automatically re-attached from the extreme tail to the center of the fuselage, and Tu-143 turns into
horizontal position. At the same time, sensor poles and landing gear are erected. When sensor poles touch
the hard surface, solid landing rockets slow the descent speed from 6m/sec to 2m/sec.
Landing parachute is jettissoned once the landing gear is loaded to avoid dragging the aircraft by the wind.

Since
1985
a target drone version of Tu-143 was built under designation M-143 (or VR-3VM, VM for aerial target).
This target drone is still used by former Soviet states. In October
2001
one of those was used during infamous Ukrainian PVO, when
missile from the S-200 long-range system destroyed Russian Tu-154 airliner over
the Black Sea.

VR-3 equipped reconnaissance squads included four launchers, carrying three
aircraft each, means of retrieval of landed aircraft, command-control post, communication unit,
unit of the data decoding and analysis and storage of extra drones.
